This is a facinating question.  I suspect that it would be necessary to temporarily re-define the CC environment variable and restore the original value when the test is completed.

What you are attempting to do is hardly ever done.

I have a few macros that I think might be useful for you.

Have a look at

YAT_LT_LINK_IFELSE(PROG, [ACTION-IF-TRUE], [ACTION-IF-FALSE])

basically works like 'AC_LINK_IFELSE' but redefines $ac_link such that the linker is called via libtool.


Cheers,
